Sample Tube O-ring Replacement
The equipment images in this topic may differ slightly from your equipment; however,
the instructions are the same unless otherwise noted.
It is important to maintain a vacuum-tight seal near the top of the sample tube stem. If an O-ring
becomes worn or cracked, it does not provide a good seal and will need to be replaced.
Before removing (or installing) a sample tube, ensure that the port valve is closed.
Observe the analyzer schematic to verify valve status.
Do not allow the sample tube connector nut drop onto the bottom of the tube as it may
break the tube.
Use the proper size frit for the sample port. The analyzer will not operate properly if an
incorrect size is used.
